For me I find the real world vulgar words break imersuon, and I would much rather people were inventive. Though at times it is the right word at the right time to convay the feeling.
I tend to do two things myself.
Using different words. For example Nebbs says "Frogs!" in place of Fu#k or similar words. This fits with her story and the nature of frogs in that.
Using more colloquial or older words. This would depend on where you drew them from. Pirate slang offers a lot for the Limsa based for example.
I'd advise making some common phrases up for your chractet , this keeps it consistent ... Like staying in the same RP clothes, it  becomes a recognised flavour of your character.
